Telling a UITextField to become first responder while embedded in a UITableViewCell

I have a UITextField that is a subview of a UITableViewCell.

When my view loads, I want the text field to become first responder. I have a pointer to the text field in the table cell, so to do this I am trying:

[myTextField becomeFirstResponder];

This returns NO all the time, regardless of when it's called, which according to the docs means the text field refused to become first responder... What am I doing wrong?

Edit:

The textfield properly responds to being touched. It bring up the keyboard then. It's only when telling it to becomefirstresponder programmatically that the problem happens.

Solution 1:

It turned out that the text field was nil when I was trying to send it first responder. Sending becomeFirstResponder later in the life cycle worked.

Solution 2:

I was having the same problem with a textfield I had added as a subview to a grouped table view cell - but figured out a solution after some poking around.

Assuming you have given the textfield a tag in your cellForRowAtIndexPath method, you can do something like this:

- (void)viewDidAppear:(BOOL)animated {
    [super viewDidAppear:animated];

    NSIndexPath *indexPath = [NSIndexPath indexPathForRow:0 inSection:0];
    UITableViewCell *cell = [self.tableView cellForRowAtIndexPath:indexPath];

    myTextField = (UITextField *)[cell viewWithTag:kMyTextFieldTag];
    [myTextField becomeFirstResponder];
}

Solution 3:

Calling it in the -(void)viewDidLoad would work.

-(void)viewDidLoad{
   [super viewDidLoad];
   // Do any additional setup after loading the view.
   [self.myTextField becomeFirstResponder] 

   //... any other code you need 
}

Solution 4:

I was not getting the cursor to show up when the UITextField was made first responder inside of the cellForRowAtIndexPath. The text field would work just fine and dandy, but it was not showing the blinking cursor inside of the field. When you would press and hold, the zoom magnify would also not show a cursor.

I got around this odd issue by setting my becomeFirstResponder inside of the didSelectRowAtIndex method.
